We stock and install DoorKing-compatible access control parts across Pasadena, with most keypad, card reader, and telephone entry replacements running $425 to $1,850 installed depending on the model and wiring condition. We carry DoorKing parts on our trucks, so a failed keypad or reader is usually back in service the same day we arrive. Most Pasadena owners discover a problem when the keypad stops accepting codes, the card reader quits recognizing fobs, or the telephone entry system rings but won’t unlock.
DoorKing access control systems take years of direct sun, sprinkler overspray, and occasional bumping from delivery vans. The plastic housings fade and crack, the membrane keypads wear through, and the circuit boards corrode faster than you’d expect. Cole Rafferty and our crew have replaced enough of these to know exactly which part failed by the second sentence of a phone call.
Which DoorKing Models This Applies To
DoorKing makes several access control lines, and the part that fits one won’t necessarily fit another. The 1812 series uses a cast aluminum housing with a magnetic lock relay built into the main board. The 1814 and 1816 models add card reader capability. The 1830 series telephone entry units have a modular keypad that separates from the main housing, and older 1810 models still running in Pasadena need retrofit plates when the keypad dies because DoorKing changed the mounting pattern.
The fastest way to identify your part is the silver tag inside the housing. It lists the model number and manufacturing date. If the tag is gone, measure the keypad face: 1812 units run roughly 7 inches wide, 1830 units closer to 9. For the OEM-versus-aftermarket decision, we stock both. DoorKing OEM keypads cost more but match the original mounting holes and weather sealing exactly. Quality aftermarket equivalents from brands like Linear and Micro-Key save money on telephone entry replacements but may need a small adapter plate. Warden Gate Repair Pasadena is an independent service provider, not affiliated with DoorKing, so we’re free to recommend whichever part actually serves you better.

Signs Your DoorKing Access Control Installation Is Failing
- Keypad works sometimes, then gives a long beep or stays dead. This is usually carbon buildup on the rubber membrane contacts. Cleaning buys a few weeks, but a 12-year-old keypad in Pasadena sun is near the end of its service life.
- Card reader clicks but the gate won’t open. The reader is reading, but a burned relay on the main board isn’t sending the open signal. You’re replacing the board, not the reader.
- Telephone entry rings but the call cuts out when you press 9. The DTMF decoder chip is failing, a common failure on 1830 series units older than 8 years. The part is on our truck.
- Housing shows cracks or the display is cloudy. Once water gets inside a DoorKing enclosure in Pasadena’s wet winters, the corrosion accelerates fast. Replacing the housing early saves the board inside.
- You hear a low hum from the box but nothing responds. The power supply transformer is failing and the board is brownout-ing. This is often misdiagnosed as a dead keypad.

AfterReplacement Cost & What’s Included
In Pasadena, a DoorKing keypad replacement typically runs $425 to $725 installed. A full telephone entry board replacement lands between $850 and $1,450. A complete new access control system with housing, reader, and reprogramming starts around $1,650 and can reach $2,300 for multi-tenant setups. What drives the range: whether your housing is still weather-tight, whether we’re reusing existing wiring or pulling new low-voltage cable, and whether you need programming for one code or forty.
Every quote includes the part, labor, wire terminations, programming, and a written price before any work starts. You approve the number, we do the work, and the 365-Day Done Right Promise means if something isn’t right, our return visit is free. Call (626) 657-5425 and tell us what it’s doing wrong, and we’ll tell you exactly what it costs to fix it before we touch a thing.
DIY or Call Us?
You can safely check a few things yourself: confirm the breaker isn’t tripped, look for loose wire nuts at the keypad, and clear spider webs from the keypad face. That’s where we’d tell you to stop. DoorKing access control wiring carries low voltage, but a shorted wire can still fry a $400 board, and bypassing a relay to force the gate open defeats the security the system exists to provide.
The boards are static-sensitive, the programming requires a master code you may not have, and mounting a new keypad so the weather seal actually seals is less obvious than it looks. If you’re in Pasadena and the system is down, call (626) 657-5425. We’ll match the part, quote the job, and send a tech whose name and photo you’ll have before they arrive.
FAQs
With Pasadena’s sun exposure, a DoorKing keypad membrane typically lasts 7 to 10 years before the buttons wear through or the contacts degrade. Units facing south or west with no shade tend to fail closer to year 7. Call (626) 657-5425 for an exact quote on replacement, and we’ll tell you what’s available for your model.
Sometimes the issue is just corroded terminals or a loose ribbon cable, which we can repair for a small labor charge. But once the membrane contacts themselves fail, there’s no practical internal repair for a DoorKing keypad. Call (626) 657-5425 and describe the symptom, and we’ll give you a straight answer on which one you’re facing.
Most single-keypad or card reader replacements are done in 60 to 90 minutes once our tech arrives. A full telephone entry system with reprogramming takes around 2 hours. Call (626) 657-5425 and we’ll give you a time window based on the specific part.
Yes, we keep DoorKing keypads, boards, readers, and housings on our trucks and at our Pasadena shop. We also stock compatible parts for LiftMaster, Mighty Mule, and Ghost Controls systems. If we need to order a rare part, we’ll tell you that on the phone before you schedule anything.
